FIELD OF THE INVENTION

Disposable premoistened multilayered cleaning wipes.

BACKGROUND OF THE INVENTION

People come into contact with many surfaces in their normal everydaylives. The propensity for surfaces to harbor viruses, bacteria, dust,dander, soil, grease, hair, and like materials is well known. As peoplecome into contact with surfaces as they move about, they are exposed tothese nefarious materials. Exposure to viruses and bacteria can resultin illness. Exposure to dust, dander, and pet hair can cause respiratorydistress. Exposure to soil and grease can result in stained clothing. Assuch, devices for cleaning surfaces are desirable.

One common device provided to consumers for cleaning surfaces is apremoistened rectangular cleaning wipe. Such wipes are commonly singlelayers of a nonwoven fibrous material, the fibrous material being pulpor polyolefin material. One limitation to such simple common wipes isthat the wipe has only one kind of texture and that texture is presumedby marketers to be efficacious on all kinds of surfaces for all kinds ofmaterials deposited on such surfaces.

In reality, the texture of surfaces and the types of materials depositedon such surfaces vary widely. For instance, the texture of the surfaceof a sofa is vastly different from a countertop surface. The type ofcleaning needed to clean the crumbs and hair from a textile at thecrease between decorative cording on a sofa and the body of a cushion iswildly different from the type of cleaning needed to clean a hardcountertop surface or the body of a textile cushion. Similarly, hair anddust have properties that are largely different from soil.

Many surfaces throughout the consumer's home have complex shapes. Forexample, many sofa designs include decorative cording around theboundary of cushions. The cording can have a generally circular crosssection and be attached to the relatively flat surface of a sofa cushionor at the intersection between two panels of fabric that form a sofacushion. When tube-like cording is attached to a flat surface, there isa crease between the flat surface and the cording. Crumbs, dust, dander,paste, hairs, and the like can accumulate in this crease and beunsightly.

In view of the wide variety of surfaces that need cleaning and thecomplex shapes that need to be cleaned, it is desirable to provide awipe having particular features that are adapted to clean a wide varietyof surfaces and detritus. With these needs in mind, there is acontinuing unaddressed need for a disposable premoistened multilayeredcleaning wipe having features adapted to clean a wide variety ofsurfaces and shapes of surfaces.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, the term “joined” refers to the condition where a firstmember is attached, or connected, to a second member either directly; orindirectly, where the first member is attached, or connected, to anintermediate member which in turn is attached, or connected, to thesecond member either directly; or indirectly.

Cleaning wipes can be practical for consumers to use for cleaning avariety of surfaces found throughout the household. For example, it canbe desirable for a consumer to use a wipe to clean counter-top surfaces,upholstery, curtains, furniture surfaces, and the like. In use, theconsumer can grasp the wipe and wipe the surface. If the wipe contains acleaning composition, the process of wiping the surface can expel atleast some of the cleaning composition onto the surface. The cleaningcomposition can contain substances, including surfactants, to helpremove soil from the surface being cleaned. As the consumer rubs thewipe against the surface to be cleaned, the wipe can lift soil from thesurface being cleaned and contain the soil in the core of the wipe or onthe surface of the wipe.

A wipe 10 is shown in FIG. 1. As shown in FIG. 1, the wipe 10 cancomprise a liquid permeable first layer 20 joined to a liquid permeablesecond layer 30. The first layer 20 and second layer 30 can be in afacing relationship with one another. The first layer 20 and secondlayer 30 can individually be generally planar webs of material ormaterials, each having a first surface 21 and second surface 22 opposingthe first surface. The wipe 10 can have a first side 330 and an opposingsecond side 340. A cleaning composition can be releasably absorbed intoone or more of the first layer 20, second layer 30, and a core, ifpresent. A cleaning composition can be releasably absorbed into theinterstitial spaces between fibers of one or more of the first layer 20,second layer 30, and a core, if present. A cleaning composition can bereleasably absorbed into the interstitial spaces between fibers of amaterial selected from the group consisting of the first layer 20,second layer 30, and the core, and combinations thereof.

FIG. 2 is a top view of a wipe 10. As shown in FIG. 2, the wipe 10 canhave a longitudinal axis L and a transverse axis T intersecting andorthogonal to the longitudinal axis L and in plane with the wipe 10. Thelongitudinal axis L can be longer than the transverse axis T. In otherwords, the length of the wipe 10 measured along the longitudinal axis Lcan be longer than the width of the wipe 10 measured along thetransverse axis T. The wipe 10 can extend between transverse edges 320that are disposed across the transverse axis T.

The wipe 10 can comprise a plurality of edges 15 to which the wipe 10extends. Said otherwise, the extent of the wipe 10 in the plane definedby the longitudinal axis L and the transverse axis T can be defined bythe edges 15. That is, the wipe 10 can extend to pairs of the edges 15.Pairs of edges 15 intersect at unique intersections 17 spread out on thewipe 10.

In use, the wipe 10 can be held generally flat in the consumer's handand wiped against a relatively flat surface in any direction. To providefor the ability to clean creases between a variety of fabrics andsurfaces, different types of intersections 17 can be provided on thewipe. For fragile fabrics such as fabric formed from knitted yarn, itmay be desirable to use a soft rounded intersection 17 to gently cleancreases so as to minimize damage to the fibrous structure of the fabric.For more sturdy surfaces, such a shoes and backpacks, it may bedesirable to have a more sharp edged cleaning implement that can deeplyand aggressively penetrate a crease to dislodge all the detrituscontained therein. It is desired that a single wipe be capable ofcleaning many different kinds of surfaces and fabric.

The intersections 17 of the edges 15 are thought to be particularlysuitable for cleaning creases. Without being bound by theory, it isthought that the intersections 17 of the edges 15 might be stiffer thanedges 15 themselves since along an edge 15 there is only one structuralelement resisting bending whereas at the intersection 17 there are twostructural elements that resist bending. Further, when force is appliedby the consumer to the intersection 17 as she penetrates a crease, theapplied stress is greater than if she would penetrate the crease with anentire edge 15 of the wipe 10, assuming that she can even fit an entireedge 15 in the crease. As such, the corners at the intersections,whether sharp or rounded, are thought to provide for enhanced utility incleaning creases as compared to straight edges, with each particularshape particularly suited for cleaning different contours of surfaces.Further, having different resistances to bending between these two partsof the wipe 10 can be beneficial in that the stiffer part can be moresuitable for cleaning one type of feature, such as the crease betweencording and fabric on a sofa, and the more flexible part can be used toclean the intersection between two materials or to lightly brush adelicate surface, such as the matting of a painting.

To provide for the ability to clean a variety of creases in and ondifferent surfaces, it is desirable to provide in the wipe 10 cornershaving different contours. At least one intersection 17 between a pairof edges 15 can comprise an arced portion 18 and at least oneintersection 17 between a pair of edges 15 can comprise an angledportion 19. An angled portion 19 is defined by the shape of two raysthat intersect at a vertex or any transition between two rays thatoccurs over a path length between the rays of less than 4 mm. An arcedportion 18 is a curved shape connecting two rays that occurs over a pathlength between the rays of greater than or equal to 4 mm. Anintersection 17 may comprise a plurality of arced portions 18, forexample as if the intersection 17 has one part that is a hyperboliccurve and another part is a circular curve.

As shown in FIG. 2, the wipe 10 can have a first quadrant 25. The wipe10 can have a second quadrant 22 on the opposite side of thelongitudinal axis L as compared to the first quadrant 25 and on the sameside of the transverse axis T as the first quadrant. The wipe can have athird quadrant 23 on the same side of the longitudinal axis L as thefirst quadrant but on the opposite side of the transverse axis T ascompared to the first quadrant 25. The wipe can have a fourth quadrant24 on the same said of the longitudinal axis L as the second quadrant 22but on the opposite side of the transverse axis T as compared to thethird quadrant 23.

The intersection 17 can comprise a circular arced portion 18 as shown inthe first quadrant 25 of the wipe 10 illustrated in FIG. 2. Theintersection 17 can comprise an arced portion 18 having varyingcurvature as shown in the fourth quadrant 24 of the wipe 10 illustratedin FIG. 2. A variety of curved shapes are contemplated with respect toshape or shapes of the intersections 17 that comprise an arced portion18.

Pairs of edges 15 can intersect such that two intersections 17 betweenpairs of edges 15 each comprise an arced portion 18 and are on opposingsides of the longitudinal axis L and opposing sides of the transverseaxis T, as shown in FIG. 2.

Pairs of edges 15 can intersect such that two intersections 17 betweenpairs of edges 15 each comprise an arced portion 18. Pairs of edges 15can intersect such intersections 17 on opposing sides of thelongitudinal axis L and opposing sides of the transverse axis T, eachcomprising an arced portion 18, and pairs of edges 15 can intersect suchintersections 17 on opposing sides of the longitudinal axis L andopposing sides of the transverse axis T, each comprising an angledportion 19, as shown in FIG. 2. Various arrangements of intersections 17having an arced portion 18 and an angled portion 19 are thought providethe use with the ability to employ both kinds of such intersections 17for cleaning without having to reposition the wipe 10 in her hand.

As shown in FIG. 2, the wipe 10 can extend to a pair of transverse edges320 spaced apart from the longitudinal axis L and a pair of longitudinaledges 32 spaced apart from the transverse axis T. Intersections 17between two pairs of the edges 15 can comprise an arced portion 18.

As shown in FIG. 3, the transverse edges 320 can be non-lineartransverse edges 320. The transverse edges 320 can be curved, straight,or a combination of straight and curved. Similarly, the longitudinaledges 32 can be curved edges, straight edges, or a combination ofstraight edges and curved edges. Without being bound by theorynon-linear transverse edges 320 may provide for improved comfort to theuser's hand when she uses the wipe 10 and may also provide for theability to clean a variety of complex shapes that might occur at theintersection between two materials.

Depending on the desired functionality that is to be imparted to thewipe 10, the number of intersections 17 that comprise an arced portion18 and the number of intersections 17 that comprise an angled portion 19can be varied. An embodiment in which all but one of the intersections17 comprise an angled portion 19 is shown in FIG. 3. Such an embodimentmight be practical if the user of the wipe 10 desires to mostly use thewipe to clean creases in household articles yet still have anintersection 17 comprising an arced portion 18 to clean intersectionsbetween two materials.

An embodiment in which all but one of the intersections 17 comprise anarced portion 18 is shown in FIG. 4. Such an embodiment might bepractical if the user of the wipe 10 desires to mostly use the wipe toclean intersections of materials in household articles yet still have anintersection 17 comprising an angled portion 19 to clean creases. Thepairs of the edges 15 can meet at intersections 17 and there can be moreintersections 17 comprising an arced portion 18 than intersections 17that comprise an angled portion 19.

A variety of shapes are contemplated for the wipe 10. The wipe 10 canhave 3 or more edges. The wipe 10 can have four edges so as to providefor a generally rectangular or square shape. The wipe 10 can besymmetric about the longitudinal axis L. Without being bound by theory,a symmetric wipe 10 might be practical to simplify manufacturing of thewipe 10 and to provide for a more intuitive use by the consumer. Thewipe 10 can comprise an even number of edges 15.

The wipe 10 can be symmetric about the longitudinal axis L, as shown inFIG. 5. Symmetry about the longitudinal axis L is thought to provideease of manufacturing and for helping the user understand andimmediately identify that different edges of the wipe 10 are designed tohave different cleaning utility. Similarly, the wipe 10 can be symmetricabout the transverse axis T for the same reasons, as shown in FIG. 6.

The wipe 10 can be symmetric about the longitudinal axis L andtransverse axis T, as shown in FIG. 7. Such a wipe 10 can provide formultiple edges 15 for the consumer to use as she cleans. Further,symmetry in both directions can signal the user that the overallorientation of the wipe 10 is not important in so far as the portion thewipe 10 interior to the edges 15 that is used to clean.

A core 40 can be between the first layer 20 and the second layer 30, asshown in FIG. 8. FIG. 8 is a view of the wipe 10 looking along thelongitudinal axis L. The core can be between the liquid permeable firstlayer 20 and the liquid permeable second layer at an intersection 17between a pair of the edges 15 that comprises an angled portion 19.Within the core 40, a cleaning composition can be releasably absorbed.

First Layer

The first layer 20 can be liquid permeable. That is, the first layer 20can provide for thru-transport of cleaning composition from a core 40 tothe first surface 21 of the first layer 20. Once the cleaningcomposition is on the first surface 21 of the first layer 20 or in thefirst layer 20, the cleaning composition can be delivered to the surfacebeing cleaned.

The first layer 20 can be superimposed over the core 40. In oneembodiment, the first layer 20 is associated with the core 40 byspray-gluing the first layer 20 to the surface of the core 40. Inanother embodiment, the core 40 can be loosely enrobed by the firstlayer 20 and second layer 30 without any points of attachment to one orboth of the first layer 20 and second layer 30. The first layer 20 canbe joined to the core 40 using any technique known in the art forjoining webs of material, including, but not limited to, ultrasonicbonding and thermal bonding. It can be practical to provide a thermallyembossed pattern on the first layer 20 of the wipe 10 to provide forbonding between the first layer 20 and the core 40.

The first layer 20 can be a material that is compliant and soft feeling.A suitable first layer 20 can be manufactured from a wide range ofmaterials such as polymeric materials, formed thermoplastic films,apertured plastic films, porous films, aperture formed films,reticulated foams, natural fibers (e.g., wood or cotton fibers), wovenand non-woven synthetic fibers (e.g., polyester or polypropylene fibers)or from a combination of natural and synthetic fibers. The first layer20 can be a nonwoven comprising polyolefin fibers. A soft compliantfirst layer 20 can provide for a pleasant interface between the wipe 10and the user's hand during use of the wipe 10.

Apertured formed films can be used for the first layer 20 since they arepervious to the cleaning composition and can be non-absorbent andhydrophobic. A surface of a formed film which is in contact with thesurface being cleaned can remain relatively dry if the formed film is oris rendered to be hydrophobic. Moreover, apertured formed films arethought to capture and retain lint, fibrous matter such as pet hair, andthe like, from the surface being treated, thereby further enhancing thecleaning benefits afforded by the wipe 10. Suitable apertured formedfilms are described in U.S. Pat. No. 3,929,135, entitled “AbsorptiveStructure Having Tapered Capillaries”, issued to Thompson on Dec. 30,1975; U.S. Pat. No. 4,324,246, entitled “Disposable Absorbent ArticleHaving A Stain Resistant Coversheet”, issued to Mullane and Smith onApr. 13, 1982; U.S. Pat. No. 4,342,314, entitled “Resilient Plastic WebExhibiting Fiber-Like Properties”, issued to Radel and Thompson on Aug.3, 1982; and U.S. Pat. No. 4,463,045, entitled “Macroscopically ExpandedThree-Dimensional Plastic Web Exhibiting Non-Glossy Visible Surface andCloth-Like Tactile Impression”, issued to Ahr, Louis, Mullane andOuellete on Jul. 31, 1984; U.S. Pat. No. 4,637,819 issued to Ouellette,Alcombright & Curro on Jan. 20, 1987; U.S. Pat. No. 4,609,518 issued toCurro, Baird, Gerth, Vernon & Linman on Sep. 2, 1986; U.S. Pat. No.4,629,642 issued to Kernstock on Dec. 16, 1986; and EPO Pat. No.0,16,807 of Osborn published Aug. 30, 1989. A suitable apertured formedfilm can be a 25 gram per square meter polyethylene vacuum formed filmsold as product ID PT02 by Clopay.

The apertures in such a first layer 20 may be of uniform size or canvary in size, as disclosed in the foregoing published documents, whichcan be referred to for technical details, manufacturing methods, and thelike. Such apertures may also vary in diameter in the manner ofso-called “tapered capillaries”. Such formed-film cover-sheets withtapered capillary apertures can be situated over the core 40 such thatthe smaller end of the capillaries face the core 40 and the larger endof the capillary faces outward. The capillary apertures can provide fortransport of the spent cleaning composition from the surface beingcleaned to the core 40. Apertures in the formed film first layer 20 canhave diameters in the range of from 0.1 mm to 1 mm, or as disclosed inthe aforesaid patent references.

The first layer 20 may comprise a plurality of first apertures passingthrough the first layer 20 and a plurality of second apertures passingthrough first layer 20. The first apertures can be larger than thesecond apertures. Each of the first apertures can have an open areabetween about 0.007 mm² to about 0.8 mm². Each of the second aperturescan have an open area between about 0.8 mm² and about 12 mm². Withoutbeing bound by theory, it is thought that by providing second aperturesof such size that soil that is lifted from the surface being wiped canbe transported through the second apertures to the core 40 and bevisible on the core 40 when the user inspects the wipe 10 after use. Thesmaller first apertures can provide for fluid transport through thefirst layer 20 both when the cleaning composition is expelled from thewipe 10 and retrieved by the wipe 10 from the surface being cleanedduring use. Further, a combination of smaller and larger apertures canbe practical for providing for adequate fluid transport through thefirst layer yet still feel dry to the touch when the user uses her handto hold the wipe 10 to rub the surface being cleaned.

The first layer 20 can be hydrophobic. However, if desired in oneembodiment, the outer and/or inner surfaces of the first layer 20 can bemade hydrophilic by treatment with a surfactant which is substantiallyevenly and completely distributed throughout the surface of the firstlayer 20. This can be accomplished by any of the common techniques wellknown to those skilled in the art. For example, the surfactant can beapplied to the first layer 20 by spraying, by padding, or by the use oftransfer rolls. Further, the surfactant can be incorporated into thepolymeric materials of a formed film first layer 20. Such methods aredisclosed in U.S. Pat. No. 5,009,653.

The first layer 20 can be a laminate of an apertured formed film asdescribed previously and a nonwoven. The nonwoven can be made of one ormore types of fibers such as those selected from the group consisting ofpolyester, polyethylene, polypropylene, bi-component fibers, wood,cotton, rayon, and combinations thereof. The nonwoven can be formed byknown nonwoven extrusion processes such as those selected from the groupconsisting of melt blowing, spunbonding, carding, and combinationsthereof. The nonwoven can be extensible, elastic, or inelastic. Thenonwoven web can comprise polyolefin fibers. The polyolefin fibers canbe selected from the group consisting of polypropylene, polyethylene,ethylene copolymers, propylene copolymers, and butane copolymers. Thenonwoven can be a 28 gram per square meter 50/50 polyethylenesheath/polypropylene core bi-component fiber. The nonwoven can be alaminate of a plurality of nonwoven webs. For instance, the nonwoven cancomprise a first layer of spunbonded polypropylene having a basis weightfrom about 6.7 grams per square meter to about 271 grams per squaremeter, a layer of melt blown polypropylene having a basis weight fromabout 6.7 to about 271 grams per square meter, a layer of melt blownpolypropylene having a basis weight from about 6.7 grams per squaremeter to about 136 grams per square meter, and a second layer ofspunbonded polypropylene having a basis weight from about 6.7 grams persquare meter to about 271 grams per square meter. The nonwoven can be aspunbonded nonwoven or a melt blown nonwoven having a basis weight fromabout 6.7 grams per square meter to about 339 grams per square meter.The nonwoven can be a 28 gram per square meter 50/50 polyethylenesheath/polypropylene core bi-component fiber. The nonwoven fibers can bejoined by bonding to form a coherent web structure. The bonding can beselected from the group consisting of chemical bonding, thermal bonding,point calendaring, hydroentangling, and needle punching.

The nonwoven can be joined to an apertured formed film using techniquesknown in the art including melt bonding, chemical bonding, adhesivebonding, ultrasonic bonding, and the like.

A laminate of a nonwoven and apertured formed film can be formed asdescribed in U.S. Pat. No. 5,628,097, issued to Benson and Curro, on May13, 1997, to form the first layer 20. For such a laminate structure, thefirst layer 20 may comprise a plurality of first apertures 200 passingthrough the first layer 20 (i.e. both the apertured formed film 41 andnonwoven 42) and a plurality of second apertures 210 passing through theapertured formed film 41 but not the nonwoven 42, as shown in FIG. 9,which is an embodiment of a first layer 20 of the wipe 10. That is, thenonwoven 42 can be free from the second apertures 210. The firstapertures 200 can be larger than the second apertures. Each of thesecond apertures 210 can have an open area between about 0.007 mm² toabout 0.8 mm². Each of the first apertures 200 can have an open areabetween about 0.8 mm² and about 12 mm². Without being bound by theory,it is thought that by providing first apertures 200 of such size thatsoil that is lifted from the surface being wiped can be transportedthrough the first apertures 200 to the core 40 and be visible on thecore 40 when the user inspects the wipe after use. The second apertures210, which can be smaller than the first apertures 200, can provide forfluid transport through the first layer 20 both when the cleaningcomposition is expelled from the wipe 10 and retrieved by the wipe 10during use. Further, a combination of smaller and larger apertures canbe practical for providing for adequate fluid transport through thefirst layer yet still feel dry to the touch when the user uses her handto rub the surface being cleaned with the wipe 10. The first apertures200 can be sized and dimensioned such that a user is able to view thecore 40 through such apertures.

The first layer 20 can comprise an apertured film. For instance, thefirst layer 20 can be a 25 gram per square meter polyethylene vacuumformed film sold as product ID PT02 by Clopay. The first layer 20 cancomprise a laminate of a film and a nonwoven having apertures throughthe laminate. The first layer 20 can comprise a laminate of an aperturedfilm and a nonwoven. The first layer 20 can comprise a laminate of anapertured film having first apertures 200 and a nonwoven, the aperturedfilm and nonwoven both having first apertures 200 there through. Thefirst layer 20 can comprise a fibrous material, such as a fibrousnonwoven comprising polyolefin fibers. The first layer 20 can be anapertured fibrous material, such as an apertured fibrous nonwovencomprising polyolefin fibers.

The first layer 20 can be a spunbond nonwoven. The spunbond nonwoven canbe apertured. The apertures can have an open area greater than about 0.1mm². The fibers of the spunbond nonwoven can be bicomponent continuousfibers. The fibers of the spunbond can be blended continuous fibers. Thefibers can be extruded and bonded in a single step. For bicomponentspunbond fibers, the components of the fiber can have two differentmelting points. For blended fibers, the component fibers of the blendcan have two different melting points. The spunbond nonwoven can have abasis weight of between about 15 grams per square meter to about 80grams per square meter.

The first layer 20 can be a coherent extensible nonwoven that is athermally bonded spun bond nonwoven web of randomly arrangedsubstantially continuous fibers. The spunbond nonwoven can bemanufactured using a conventional spunbond process. Molten polymer isextruded in continuous filaments that are subsequently quenched,attenuated by a high velocity fluid, and collected in a randomarrangement on a collecting surface. After collection of the fibers,thermal, chemical, or mechanical bonding can be performed on the fiberto form the spun bond nonwoven. The first layer can be a spunbondnonwoven referred to as SOFSPAN 200 available from Fiberweb.

Core

The core 40 can be a material that can releasably absorb a cleaningcomposition. In practice, the voids within the core 40 can act as areservoir for the cleaning composition, the cleaning composition beingstored within the capillaries within the core 40. The core 40 can be afibrous material in which the capillaries are provided by theinterstitial spaces between the fibers of the core 40. The core 40 canbe an open celled foam in which the capillaries are provided by theinterconnected pores within the foam. The core 40 can comprise anonwoven. An economical core 40 can be provided by a nonwoven comprisingpolyolefin fibers.

The core 40 can comprise a layer of cellulosic material. The core cancomprise an 80 gram per square meter nonwoven of bicomponent fibers, thebicomponent fibers comprising a polyethylene sheath and a polyethyleneterephthalate core having a loft of about 2.5 mm. The bicomponent fiberscan provide for structural integrity of the core 40 when bonded. Havingan appreciable weight fraction of the core 40 made of cellulose can beeconomical and technically sound since cellulose is known to highlyabsorbent.

The core 40 can comprise a multi bonded air-laid core. The core 40 cancomprise a multi bonded air-laid core comprising about 15% by weightbicomponent fibers having a polyethylene sheath and polyethyleneterephthalate core, about 2.5% by weight latex, about 82% by weightpulp, and a basis weight of about 135 grams per square meter. Thebicomponent fibers can provide for structural stability and rigidity ofthe core 40 and the latex can aid in bonding the different components ofthe core 40 together.

The core 40 can comprise a thermally bonded air-laid core. The core 40can comprise a thermally bonded air-laid core comprising about 18% byweight bicomponent fibers having a polyethylene sheath and polypropylenecore and about 82% pulp.

The core 40 can comprise a laminate of an 80 gram per square meternonwoven of bicomponent fibers, the bicomponent fibers comprising apolyethylene sheath and a polyethylene terephthalate core having a loftof about 2.5 mm and two layers of a multi bonded air-laid corecomprising about 15% by weight bicomponent fibers having a polyethylenesheath and polyethylene terephthalate core, about 2.5% by weight latex,about 82% by weight pulp, and a basis weight of about 135 grams persquare meter. The core 40 can be a single layer thermally bonded pulpcore that is 90% by weight pulp and 10% by weight bicomponentpolyethylene/polypropylene fibers.

The core 40 can comprise open celled foam. For instance, the core 40 cancomprise open celled foam formed from a high internal phase emulsion,such as the open celled foam described in U.S. Pat. No. 5,387,207,issued to Dyer, DesMarais, LaVon, Stone, Taylor, and Young, on Feb. 7,1995. Open celled foams can be desirable since they can provide for alarge storage volume of cleaning composition relative to the mass of thecore 40.

The core 40 can comprise a material selected from the group consistingof polyolefin fibers, cellulose fibers, rayon, open celled foam, andcombinations thereof.

The functions of the core 40, if present, are to store a cleaningcomposition prior to use, dispense cleaning composition when the wipe 10is used to clean a surface, reabsorb spent cleaning composition aftercleaning, and retain soil that has been removed by the cleaning effort.The core can have a storage volume of about 19 ml. The core can have astorage volume of between about 5 mL and about 30 mL in an uncompressedstate. The core can have a storage volume of between about 12 mL andabout 25 mL in an uncompressed state. The core can have a storage volumeof between about 16 mL and about 25 mL in an uncompressed state.

Second Layer

The second layer 30 can be liquid permeable. That is, the second layer30 can provide for thru-transport of liquid cleaning composition from acore 40 to the second surface 22 of the second layer 30. The secondlayer 30 can be superimposed under the core 40 so that the core 40 isbetween the first layer 20 and second layer 30. In one embodiment, thesecond layer 30 can be associated with the core 40 by spray-gluing thesecond layer 30 to the surface of the core 40. In another embodiment,the core 40 is loosely enrobed by the first layer 20 and second layer 30without any points of attachment. The second layer 30 can be joined tothe core 40 using any technique known in the art for joining webs ofmaterial, including, but not limited to, ultrasonic bonding and thermalbonding.

The second layer 30 can be a material that is compliant and softfeeling. The second layer 30 can be any of the materials as describedpreviously as being suitable for the first layer 30. It can also bepractical for the second layer 30 to be an abrasive layer.

Abrasive Layer

The wipe 10 can have an abrasive layer. The abrasive layer of the wipe10 can be the second layer 30 of the wipe 10. Arranged as such, thefirst layer 20 can provide for a soft compliant wiping surface and theabrasive layer can be on the side of the core 40 opposite the firstlayer 20. In a simple construction, the wipe 10 can have 3 layers, afirst layer 20, an abrasive layer being the second layer 30, and a core40 disposed between the abrasive layer and first layer 20.

It is contemplated that the second layer 30 can be positioned such thatthe second layer 30 is between the abrasive layer and the core 40. Forinstance, as shown in FIG. 1, the second layer 30 can be the abrasivelayer of the wipe 10. If the abrasive layer is the second layer 30,other layers of material may be between the abrasive layer and core 40,but are not necessarily needed.

If other layers are provided between the abrasive layer and the core 40,such other layers can have other functional attributes and one or moreof those layers can be considered to be the second layer 30 as describedherein.

The abrasive layer can be liquid permeable. That is, the abrasive layercan provide for thru-transport of liquid from a core 40 from the firstsurface 21 to the second surface 22 of the abrasive layer. The abrasivelayer can be superimposed over the core 40. In one embodiment, theabrasive layer is associated with the core 40 by spray-gluing theabrasive layer to the surface of the core 40. In another embodiment, thecore 40 is loosely enrobed by the first layer 20 and abrasive layerwithout any points of attachment. The abrasive layer can be bonded tothe core 40 using any technique known in the art for joining webs ofmaterial, including, but not limited to, ultrasonic bonding and thermalbonding.

A suitable abrasive layer can be manufactured from a wide range ofmaterials such as polymeric materials, formed thermoplastic films,apertured plastic films, porous films, aperture formed films,reticulated foams, natural fibers (e.g., wood or cotton fibers), wovenand non-woven synthetic fibers (e.g., polyester or polypropylene fibers)or from a combination of natural and synthetic fibers.

The abrasive layer can be a material that provides an abrasive surfaceof the wipe 10. In use, an abrasive layer that is rough can help todislodge soil from the surface being cleaned and can help pick up loosefibers such as dust, lint, dander, pet hair, and the like from thesurface being cleaned. Further, an abrasive layer may help fluff up thefibers in textiles that are being cleaned thereby allowing for betterapplication of the cleaning composition to the textile surface beingcleaned.

The abrasive layer can comprise a net material. The net material can bea net comprised of at least two sets of strands wherein each set ofstrands crosses and interconnects another set of strands at asubstantially fixed angle wherein strands in each set extend along arespective direction and are in substantially co-planar, spaced-apartrelationship. The net material can be polypropylene or other suitablydurable polyolefin material. The abrasive layer can be a material suchas that sold under the trade name DELNET, by Delstar Technologies, Inc.,Middletown, Del.

The abrasive layer can comprise a composite material 99 such as any ofthe materials described in U.S. Pat. No. 7,917,985 issued to Dorsey etal. on Apr. 5, 2011. For instance, as shown in FIGS. 10A and 10B, theabrasive layer 50 can comprise a net material 100 comprising at leasttwo sets of strands 110 wherein each set of strands 110 crosses andinterconnects another set of strands 110 at a substantially fixed anglewherein strands 110 in each set of strands 110 extend along a respectivedirection and are in substantially co-planar, spaced-apart relationshipthat is bonded to a substrate 120 wherein a plurality of the strands 110are broken forming raised whiskers 130 that extend away from thesubstrate 120, as shown in FIGS. 10A and 10B. The abrasive layer 50 canbe positioned to form the wipe 10 such that the whiskers 130 extend awayfrom the core 40. That is, the second side of the wipe 10 can havewhiskers 130. As the wipe 10 can be constructed, the substrate 120 canbe between the net material 100 and the core 40. Together, the netmaterial 100 and substrate 120 can form an outer layer of the wipe 10that is the second side of the wipe 10.

The net material 100 can be a 51 grams per square meter polypropylenenet (style number RO412-10PR) made by Delstar Technologies, Inc.,Middletown, Del., and sold under the trade name DELNET. The net material100 can be polypropylene net (style number RC0707-24P) made by DelstarTechnologies, Inc., Middletown, Del., and sold under the trade nameDELNET.

The net material can have 40 strands per inch in the machine directionand 13 strands per inch in the cross direction that are bonded to oneanother, together forming the two sets of strands 110. The net materialcan be polypropylene fine square structure net referred to as PF40 andsold by Smith and Nephew Extruded Films, East Yorkshire, England. Thenet material 100 can be thermally bonded to one or more layers of asubstrate 120 to form composite 99.

The substrate 120 can be a nonwoven or woven material. The substrate canbe one or more layers of 60 grams per square meter 50% polypropylene 50%rayon spun laced nonwoven fabric. The substrate 120 can be a 60 gram persquare meter polypropylene polyethylene copolymer. The substrate 120 canbe SOFSPAN 120, available from Fiberweb. The composite 99 can bestressed to break a plurality of the strands 110 to form the whiskers130. The stress can be provided, for instance, by a ring rolling processas described in U.S. Pat. No. 7,917,985 issued to Dorsey et al. on Apr.5, 2011.

In one embodiment of the wipe 10, it can be practical for the abrasivelayer 50 to be translucent. Such translucency can provide the user theability to examine the second side of the wipe and observe that acolored second layer 30 is between the abrasive layer 50 and the core40. A translucent abrasive layer 50 can be provided by an uncolored orlightly colored abrasive layer.

Free Liquid Cleaning Composition

To aid in cleaning, the wipe 10 can be provided with a free liquidcleaning composition. The free liquid cleaning composition can bereleasably absorbed in the core 40. That is, the volume of the freeliquid cleaning composition is held within the voids of the core 40 bycapillary forces. For example, the free liquid cleaning composition canbe held by surface tension within the interstitial spaces between fibersor within the cells of an open celled foam forming the core 40. The freeliquid cleaning composition can be expelled from the core 40 bycompressing the core 40. The core 40 can reabsorb spent cleaningcomposition into voids within the core 40 by capillary forces. Thecapillary forces can act to draw spent cleaning composition through thefirst layer 20 to the core 40.

The free liquid cleaning composition is an unencapsulated liquidcleaning composition. The free liquid cleaning composition can bereleasably absorbed in a material selected from the group consisting offirst layer 20, second layer 30, core 40, and combinations thereof. Thefree liquid cleaning composition can be releasably absorbed inconstituent fibers of a material selected from the group consisting offirst layer 20, second layer 30, core 40, and combinations thereof.

One practical formulation of the cleaning composition is set forth inTable 1.

TABLE 1 Cleaning composition formulation. Ingredient % Active by WeightFunction Distilled water Quantity sufficient to Solvent balance to 100%Sodium lauryl sulfate 0.90 Anionic surfactant C12/14 amine oxide 0.30Cationic surfactant Glycol Ether PPh 1.50 Solvent Citric Acid 50% Traceas needed to target pH adjustment, pH of 7 builder Korolone B-119 0.01Preservative Perfume 0.02 Perfume Dow Corning DC 2310 0.02 Antifoam

The cleaning composition can comprise between about 0.001% to about 10%by weight of the liquid cleaning composition of surfactant. The cleaningcomposition can comprise between about 0.1% to about 5% by weight of theliquid cleaning composition of surfactant. The cleaning composition cancomprise between about 0.1% to about 4% by weight of the liquid cleaningcomposition of surfactant. The cleaning composition can comprise betweenabout 0.1% to about 3% by weight of the liquid cleaning composition ofsurfactant. The cleaning composition can comprise between about 0.1% toabout 2% by weight of the liquid cleaning composition of surfactant.Without being bound by theory, it is thought that lower mass fractionsof surfactant might result in less observable residual cleaningcomposition left on a surface after cleaning. Higher mass fractions ofsurfactant might result in ringing and spotting from a locally heavyapplication of the cleaning composition to the surface being cleaned.

The cleaning composition can comprise 0.001% to 0.1% by weight of anantifoam compound. A non-limiting example of an antifoam compound is DowCorning DC 2310.

The cleaning wipe 10 can comprise between about 5 g to about 40 g ofcleaning composition. The cleaning wipe 10 can comprise between about 15g to about 30 g of cleaning composition.

Wipe

The wipe 10 as contemplated herein can have two sides, each having adifferent function. For instance, one side of the wipe can have a softcompliant surface for wiping a surface or fabric to remove lightsoiling, dust, and lint and the other side can have an abrasive surfacethat can dislodge agglomerations of soil or alter the surface of atextile so that a cleaning composition can be effectively delivered toand retrieved from the textile.

A premoistened wipe 10 having a longitudinal axis L is shown in FIG. 11.The wipe 10 can have a liquid permeable first layer 20 joined to aliquid permeable second layer 30. The first layer 20 and the secondlayer 30 can be in a facing relationship with one another. By facingrelationship, it is meant that the two components rest generally flatrelative to one another so that one planar surface of one componentfaces a planar surface of the other component, like a floor mat rests onthe floor. Two components can be in a facing relationship yet still haveother components positioned between the two components that are in afacing relationship, for instance like a sandwich that has a slicecheese positioned between two slices of bread that are in a facingrelationship.

For instance, the wipe 10 can be designed so that the core 40 is absentbetween the first layer 20 and second layer 30 proximal the transverseedges 320. The first layer 20 and the second layer 30 can be joineddirectly to one another so that the first layer 20 and second layer 30are in direct contact with one another.

As shown in FIG. 11, the first layer 20 and second layer 30 can bejoined to one another along each transverse edge 320. The first layer 20can be an apertured film, and apertured formed film, a nonwoven, wovenmaterial, or a composite material of such constituents.

The wipe 10 can have a variety of constructs including any of thosediscussed previously. In the construction shown in FIG. 1, the firstlayer 20 and second layer 30 can be joined to one another, for instanceby melt bonding, chemical bonding, adhesive bonding, ultrasonic bonding,and the like. The first layer 20 and second layer 30 can be joined toone another along the transverse edges 320. The transverse edges 320 arespaced apart away from the longitudinal axis L. The transverse edges 320can be straight lines or nonlinear, for instance a decorative scallopedpattern. The first layer 20, second layer 30, and core 40 can becoextensive with one another along the longitudinal axis L, as shown inFIG. 1. The first layer 20, core 40, and second layer 30 can be joinedtogether at the longitudinal ends of the wipe 10, as shown in FIG. 6. Inan alternative arrangement, the first layer 20 and second layer 30 canbe joined to one another along the transverse edges 320 and along thelongitudinal ends to form a pocket in which the core 40 is positioned.In such an arrangement, the first layer 20 and second layer 30 can belongitudinally more extensive than the core 40 so that at thelongitudinal ends of the wipe 10, the core 40 is not between the firstlayer 20 and second layer 30. That is, the longitudinalends/longitudinal edge bonds of the wipe 10 can be free of material fromthe core 40. The first layer 20 and second layer 30 can extendlongitudinally beyond the core 40 and extend further away from thelongitudinal axis L than the core 40, thereby forming a pouch withinwhich the core 40 is positioned. Arranged as such, the transverse edges320 can be free of material from the core 40.

As shown in FIG. 12, the wipe 10 can comprise a pair of longitudinaledge bonds 400 disposed at opposing longitudinal edges of the wipe 10across the longitudinal axis L. Each longitudinal edge bond 400 cancomprise material from the first layer 20, the core 40, and the secondlayer 30. By having longitudinal edge bonds 400 that include the core40, the longitudinal edge bonds 400 can have a greater resistance tobending as compared to other portions of the wipe 10, for instance ascompared to the transverse edge bonds 410. The longitudinal edge bonds400 can have a greater resistance to bending than the transverse edgebonds 410 of the wipe 10. Having a different resistances to bendingbetween these two parts of the wipe 10 can be beneficial in that thestiffer part can be more suitable for cleaning one type of feature, suchas the crease between cording and fabric on a sofa, and the moreflexible part can be used to lightly brush a delicate surface, such asthe leaf of decorative plant.

Resistance to bending can be measured by separating the relevant bondfrom the wipe and using a two point bending test with the resistance tobending quantified as the force required to deflect the free end of thebeam of bond material 10% of the length of the beam of bond material.

Similarly, the longitudinal edge bonds 400 can be thicker than thetransverse edge bonds 410, the thickness being measured orthogonal tothe longitudinal axis L and out of plane with respect to the first layer20 and the second layer 30. This difference in thickness can provide forthe availability of the wipe 10 to fit into different size cracks,crevices, and creases.

Stiff longitudinal edge bonds 400 can be useful for cleaning narrowcreases and folds in surfaces. If the longitudinal edge bonds 400 arefloppy, as might be the case if only the first layer 20 and second layer30 are bonded to one another to enclose the core 40, it might bedifficult for the user to slip the wipe 10 edgewise into a narrowcrease, crevice, or fold. It is thought that the stiff longitudinal edgebonds 400 can be useful for cleaning the crease between the sole of adress shoe and the body of the shoe. The stiff longitudinal edge bonds400 might also be useful for cleaning the crease between the textile ona sofa and decorative cording that is commonly found around the edges ofcomponents of the sofa such as the cushions, arm rests, and decorativecontours, where dirt, food crumbs, dander, and pet hair oftenaccumulate. The stiff longitudinal edge bonds 400 might also be usefulfor cleaning between the keys of a computer keyboard or piano, withinthe contours of the facings and buttons of electronic devices such astelevisions and stereos, around the edges of picture frames, and otherhard to reach narrow creases, cracks, and crevices.

If desired, the longitudinal edge bonds 400 can be continuous orintermittent. Continuous longitudinal edge bonds 400 can be stiffer thanintermittent longitudinal edge bonds.

Longitudinal edge bonds 400 can be provided for by thermally bonding thefirst layer 20, second layer 30, and core 40 to one another. As shown inFIG. 12, the longitudinal edge bonds 400 can have a longitudinal edgebond minimum thickness TB and the wipe 10 can have a maximum thicknessTL along the longitudinal axis L. The longitudinal edge bond minimumthickness TB and the maximum thickness TL are both measured orthogonalto the longitudinal axis L and out of plane with respect to the firstlayer 20 and the second layer 30. The longitudinal edge bond minimumthickness TB can be less than about 80% of the maximum thickness TL. Thelongitudinal edge bond minimum thickness TB can be less than about 30%of the maximum thickness TL. Without being bound by theory, it isthought that relatively thin longitudinal edge bonds 400 can bebeneficial in that they can readily enter narrow creases, cracks, andcrevices and be used to clean such features. Further, by having a fatterpart of the wipe 10 somewhat away from the thin longitudinal edge bond400 the wipe can be stuffed to fit into narrow cracks, creases, andcrevices, thereby providing for better cleaning, particularly around theexit from such features which may be the most visually apparent portionof the feature.

The maximum thickness TL of the wipe 10 can be between about 3 mm toabout 10 mm, or about 3 mm to about 8 mm, or 3 mm to about 6 mm.Longitudinal edge bonds 400 that comprise the first layer 20, secondlayer 30, and core 40 can have a longitudinal edge bond minimumthickness TB between about 0.1 mm and 2.4 mm. The thickness of thelongitudinal edge bonds 400 and the transverse edge bonds 410 can becontrolled by, for example, altering the pressure and/or heat appliedthat portion of the wipe 10 to form the respective bond. Higher pressureand greater amounts of heat can be associated with stiffer and orthinner bonds.

The second layer 30 can be a layer that is an interior component of thewipe 10, as shown in FIG. 13. As shown in FIG. 13, the core 40 can bepositioned between the first layer 20 and the second layer 30. Thesecond layer 30 can be colored, as described previously, for instance bya dye, pigment, ink, or other technique. The second layer 30 can bebetween the core 40 and the abrasive layer 50. The abrasive layer 50 canform an exterior surface of the wipe 10 that can be used to dislodgesoil from the surface being cleaned. The first layer 20, second layer30, and abrasive layer 50 can be joined to one another along thetransverse edges 320, for instance by thermally bonding the threematerials together. The second layer 30, if colored, can be visiblethrough the first layer 20 at positions where the first layer 20 andsecond layer 30 are joined to one another and the core 40 is not betweenthe first layer 20 and second layer 30.

As shown in FIG. 14, the abrasive layer 50 can be the second layer 30.That is, the wipe 10 can comprise first layer 20 and a second layer 30and a core 40 positioned between the first layer 20 and second layer 30,wherein the second layer 30 is an abrasive layer 50. The abrasive layer50 can be colored. The abrasive layer 50 can be colored with a materialselected from the group consisting of dye, pigment, ink, andcombinations thereof.

The first layer 20 can form a first side 330 of the wipe 10. As shown inFIGS. 15 and 16, the first side 330 of the wipe 10 can comprise one ormore channels 250 embossed into the core 40. Embossed channels 250 canincrease the stiffness of the wipe 10 and increase the durability of thewipe 10.

The embossed channels 250 can provide for pillowed regions on the wipe10 which impart a three-dimensional surface profile from the generallyplanar surface of the first layer 20. Channels 250 can be embossed intothe wipe 10 in any manner known in the art including embossing, fusionbonding, thermal bonding, and the like for impressing a pattern upon asubstrate. Without being bound by theory, it is thought that channels250 provide for regions of a fibrous substrate that have a highercapillary potential than regions of the fibrous substrate that aredevoid of channels 250. The increased capillarity is provided for by theclose proximity of the fibers constituting the fibrous substrate.Channels 250 can provide for pathways of enhanced capillarity throughoutthe wipe 10, thereby promoting widespread distribution of the liquidcleaning composition in the wipe 10.

The channels 250 can be continuous channels 250. The channels can bediscontinuous channels 250. Discontinuous channels can provide for thepathways of enhanced capillarity in the same manner as continuouschannels 250 provided that the spacing between channel segments 26 ofthe channel 250 are sufficiently small so that fluid can still beconducted from one channel segment to another. For discontinuouschannels, the spacing between segments of the channel 250 can be lessthan the length of the channel segments 26.

A channel 250 can extend away from a longitudinal edge 32. Thelongitudinal edge 32 can extend across the longitudinal axis L. Byhaving the channel 250 extend all the way to the longitudinal edge 32,the liquid cleaning composition might be distributed all the way to theopposing longitudinal edge 32 of the wipe 10, thereby providing enhancedefficacy of the wipe 10. The wipe 10 can comprise a plurality ofchannels 250 each of which extend away from or proximal to thelongitudinal edge 32, with an increased number of channels 250 thoughtto provide for enhanced distribution of the cleaning composition. One ormore channels 250 can extend from one longitudinal edge 32 to anopposing longitudinal edge 32. That is, one or more channels 250 canextend between the longitudinal edges 32. Such an arrangement can bepractical for distributing cleaning composition along the entire extentof the wipe 10 in longitudinal direction. Further, channels 250 that aregenerally oriented in the longitudinal direction can provide forenhanced stiffness of the wipe 10 with respect to bending about thetransverse axis T.

A channel 250 can be formed in one or more layers of the wipe 10, asshown in FIG. 12. A channel 250 can comprise material from one or moreof the first layer 20, the core 40, and the second layer 30. A channel250 can comprise a material selected from the group consisting of thefirst layer 20, the core 40, the second layer 30, and combinationsthereof. Channels 250 in one or more of the layers comprised of anonwoven material can be practical. The wipe 10 can compriseintersecting channels 25. Optionally, the channels 250 can be spacedapart from one another.

A channel 250 need not extend all the way to the longitudinal edge 32.The wipe 10 can have one or more longitudinal edge bonds 400. A channel250 can extend away from the edge bond 400. It is contemplated hereinthat the wipe 10 can comprise a plurality of such channels 250. Thechannels 250 can extend away from the longitudinal edge bond 400 to anopposing longitudinal edge bond 400. As described and shown herein, thelongitudinal edge bond 400 can comprise material selected from the groupconsisting of the first layer 20, the second layer 30, the core 40, andcombinations thereof. The longitudinal edge bond 400 can provide for adense fibrous structure having high capillarity.

Channels 250 can also be beneficial for helping the wipe 10 maintaindistribution of the cleaning composition in the wipe 10 when the wipe 10is packaged such that the package is designed so that one of thelongitudinal edges 32 is oriented towards the bottom of the package. Insuch an arrangement, if the pore sizes of the materials constituting thewipe 10 are so large such that the capillary potential of any part ofthe wipe 10 is less than the length of the wipe 10 along thelongitudinal axis L, the wipe 10 may not be wetted across the entirelength along the longitudinal axis L. The channels 250 can help draw upany cleaning composition that is contained in the bottom of the packagehigher up into the wipe in the longitudinal direction. The depth of thechannels 250 can be greater than about 0.25 mm.

One or more channels 250, continuous or segmented, can extend betweenthe transverse edge bonds 320. Plurality of channels 25, continuous orsegmented, can extend between the transverse edge bonds 320. Suchchannels 250 can promote distribution of the cleaning compositionlaterally in the transverse direction and provide for enhanced bendingstiffness about the longitudinal axis L. One or more channels 250,continuous or segmented, can extend between the transverse edges 320.

The wipe 10 can comprise a first layer 20, second layer 30 in facingrelationship with the first layer 20, a plurality of channels 25, and afree liquid cleaning composition releasably absorbed in wipe 10. Thecleaning composition can be releasably absorbed in a layer selected fromthe group consisting of the first layer 20, the second layer 30, core40, and combinations thereof. A core 40 can be disposed between thefirst layer 20 and the second layer 30. The channels 250 can extend fromthe longitudinal edge 32. The channels 250 can extend proximal to thelongitudinal edge 32. The channels 250 can extend between thelongitudinal edges 32. The channels 250 can extend from the transverseedge 320. The channels 250 can extend proximal to the transverse edge320. The channels 250 can extend between the transverse edges 320. Thechannels 250 can extend to within less than about 10 mm of thelongitudinal edge 32 and or transverse edge 320.

Since the wipe 10 can be designed to use as a hand implement, the wipe10 can be sized and dimensioned to conform to an adult human hand. Forinstance, the wipe 10 can have a length, as measured along thelongitudinal axis L of between about 8 cm and about 14 cm. The wipe 10can have a maximum width, as measured orthogonal to the longitudinalaxis L and in plane with the first layer 20 of between about 5 cm andabout 12 cm.

Fluid Expression

To provide for different sides of the wipe 10 having differentfunctions, it can be practical to make the first side 330 express liquidcleaning composition from the core 40 at a different amount or rate ascompared to the second side 340. For instance, if the first side 330 ofthe wipe 10 is being used by the consumer for wiping a sofa, the user'sobjective may be removal of light dust and pet hair. The cleaningcapability of the wipe 10 for cleaning light dust and pet hair may notrequire as much cleaning composition to be effective as compared to acleaning effort on more heavily soiled surfaces employing the secondside 340 of the wipe 10. As such, it may be beneficial to have firstside 330 express liquid more slowly or in a lower quantity than thesecond side 340. The quantity of liquid cleaning composition expressedfrom a particular side of the wipe 10 can be quantified by thecumulative wipe fluid loss value. To provide for a marked difference incleaning composition expression, the first side 330 and second side 340can each have an individual cumulative wipe fluid loss value and thecumulative wipe fluid loss value of the first side 330 and thecumulative wipe fluid loss value of the second side 340 can differ bymore than about 10%. Such a difference can provide for a user noticeabledifference in cleaning composition expression from the first side 330 ascompared to the second side 340. If desired, the cumulative wipe fluidloss value of the second side 340 can be more than about 10% greaterthan the cumulative wipe fluid loss value of the first side 330. Such anarrangement can be practical if the first side 330 is designed for lightcleaning and the second side 340 is designed for more heavy cleaning.

The cumulative wipe fluid loss value is measured as follows. A stack oflayers of Ahlstrom filter paper grade 989 supplied by EmpiricalManufacturing Company (or equivalent) is provided. The number of layersneeds to be sufficient so that at least the bottom 3 layers aresubstantially dry after completion of the test so that the stack offilter paper is not wetting through. A layer is considered substantiallydry if the percent change in the mass of the layer in percent post-testas compared to the pre-test dry mass is less than 1%. The dimensions ofeach layer of filter paper need to extend laterally beyond the wipebeing tested by 13 mm. The filter paper is conditioned in advance of thetest for at least 12 hrs at a temperature of 21.1° C.+/−1° C. and arelative humidity of 65% and the measurement of the cumulative wipefluid loss value is measured under the same conditions. The wipe istemperature conditioned for 12 hours at 21.1° C.+/−1° C. The wipe istested in its as wetted state.

The wipe being tested, which has cleaning composition absorbed therein,is weighed using a Sartorius E2000D laboratory balance. Then the wipe isplaced flat and centered onto the stack of filter paper. A rigidnon-porous weight having an area greater than the area of the wipe isapplied to the wipe so that the pressure applied to the wipe is 5.59kPa+/−0.34 kPa. The area used to compute the pressure is the plane areaof the wipe minus the area of any bond(s) about the periphery of thewipe.

The pressure is applied to the wipe within 1 second in a manner suchthat the pressure applied does not exceed 5.59 kPa+/−0.34 kPa at anytime during the pressure application and then left on the wipe so thatthe total pressure is supported by the wipe for 30 seconds. After 30seconds, the applied pressure is removed and the wipe is immediatelyweighed using the laboratory balance. The difference in weight of thewipe before the pressure is applied and after the pressure is appliedand removed is the cumulative wipe fluid loss value for the side of thewipe facing the filter paper layers. A fresh wipe and fresh filter paperis used for each measurement of cumulative wipe fluid loss value that ismade.
